Which iPod should I get?

Question

I am currently using a 5th generation iPod classic and the battery has gotten very bad, as it won't hold a charge longer than 4-and-a-half hours. So, I am faced with a few options here:
1. Buy a 2nd Generation Shuffle ($79)
2. Send in current iPod for a new battery ($79)
+- the current iPod has two scratches on the screen+
3. Send in current iPod for a refurbished iPod ($140)
4. Buy an iPod Nano ($150)
I am also planning on buying an iPhone either this summer or next summer (the 3rd generation or the 4th generation). The new iPod from the list above would have to last until either summer.
Thank you for reading this, I need a new iPod, but there are so many options, I wanted to take this to the community.

1. The 2nd gen iPod shuffle costs $49 for the 1GB model ($39 on Apple's refurb page). The new iPod shuffle is 3rd gen. A shuffle will not take the place of an iPod that has a screen and can play video.
I was referring to a 2GB shuffle that can still be found on Amazon and at Best Buy.
Although now looking back on the subject, a shuffle would be a major difference then what I am used to.
I will, however, look into those websites that I can use to repair my current iPod. One of the scratches is fairly deep and I'm unsure if that scratch removal kit would get rid of it.
I also remembered that I do have an old 2nd generation iPod Nano and I could use that for the time of being, until I can repair my current iPod or buy an iPhone.
3. Send in current iPod for a refurbished iPod ($140)
You don't get to choose to replace your iPod if only the battery is bad.
Assuming you have the 5th gen iPod video with 60 GB;
If only the battery is bad, it will be replaced for $59.
If the hardware other than the batery is bad, it can be replaced for $149
I have a 30 GB model. I called Apple Technical Support and I was told that I can send my iPod in for a new battery ($59*), or just send it in for a refurbished model ($149).
*I can't quite remember what she said, but it was between $60 and $70.
I am also planning on buying an iPhone either this summer or next summer (the 3rd generation or the 4th generation).
The current iPhone is the 2nd gen. It is called 3G because it uses the +3G wireless network+. So if there is a new one introduced this summer, it will be the 3rd gen iPhone. Apple will not necessarily introduce a new iPhone every summer.
I know the current iPhone 3G is only the 2nd generation; I was talking about the new iPhone. I was just making an assumption that a new iPhone was being released this summer, since Apple tends to update their products annually and the iPhones have been released around July. :P
Thank you guys for the helpful input! I will soon figure something out based on your suggestions!
