Upgrading Mac Mini 2.1 (2007/08) from 1GB to 4GB RAM

Question

Just joined, this is my first question.
Done plenty of reading on macupgrades; everymac; eshop.macsales; and macminiramupgrade..............so I know what I want to do and just want someone to confirm the right spec RAM if I give you a couple of part numbers of what I plan to purchase. Firstly:-
I have done the checks and my Mac Mini is a 2.1, 2007/08, annoyingly bought just before the next generation came out in the spring of 2009. The model ref is A1176. It only has 1gb (2 x 512mbs) of RAM. The main objective is to take advantage of icloud now we have two other apple devices (iphone4s and Ipad2). So to get there I have to upgrade the operating system from Leopard to Snow Leopard (which needs 1gb of RAM) and then upgrade again to Lion (which critically needs 2gb of RAM). Fundamentally it is imperative I upgrade the RAM and if I am going to have a go at that I might as well go to the limit of what my Mac Mini can take and I believe it can take just over 3gbs according to what I have read. That means using a 4gb kit (2 x 2gbs).
I have scrutinised the spec of the recommended RAM on macupgrades but that is with a view to only upgrading to 2gbs (2 x 1gb). They quote a Kingston 1GB DDR2 PC5300 SODIMM 200 PIN, unbuffered, non EEC etc. I cannot find any detail on the help websites that quote a 2x2gb upgrade (on my Mac Mini) although as I said I know it can be done even though you won't be able to use the whole 4gb.
I have found 2GB RAM from safe manufacturers such as Crucial and Kingston which are exactly the same spec. Please can someone have a look at and say that will do it?
Quick find code on Ebuyer.com for Kingston RAM is 121416..................just done it and it goes straight to the relevant page.
Went to the Crucial.com website for their product, put in the code CT2KIT25664AC667 in the search field and went straight to the product.
Always appreciate help from those in the know.

OWC is a US site which does ship overseas.  You could look at the Samsung 2GB memory they carry and see if you can get it locally. It's Samsung part number M470T2953CZ3-CE6. I've had good luck with Samsung memory in various mac systems.
While you didn't ask this, you probably know that the benefit to using two 2GB memory (versus 2+1) is that the Intel architecture will run a little faster, around 3% to 5%+, since matched memory enables dual channel memory access. 
See this article about installing Lion over Leopard. Snow Leopard is no longer available from Apple stores or Apple online. In the US, and I would assume other countries that have an Apple online store, you can call and order Snow Leopard off the legacy products list. Likewise, Lion is no longer available for download. However, you can contact the Apple online store and they can either sell you the USB stick with Lion on it, or, in the US I'm told they can sell you a code to download Lion online. That may require Snow Leopard if done through the App store.
I'm bouncing around a little here, so bear with me. On your question of Lion running in 3GB, not knowing exactly what you're running, I really can't answer that. I can point out that some people have been OK with Lion in 2GB, however, as you've read, many others have required a memory upgrade to, typically, 4GB. Right now, the Lion system I'm on is an iMac that is only using 2.98GB in wired+active memory. Applications running are mail, Chrome browser, and activity monitor.
You may want to post a discussion question in the Lion discussion area here on others 3GB (2x2GB memory cards) Lion experience on your 2007/2008 mini 2,1.   Or of course on the mini discussion here.
If I've confused more than helped, I plead that it's been a long day! Any other questions, please let me know.
