OSX upgrade late 2007 macbook

[sailor720]

I have a late 07 macbook, 2ghz, 2gb ram running 10.5.8. I am starting to run into issues with being unable to run flash as chrome no longer supports 10.5 so I am thinking of upgrading. I can buy snow leopard for $20 and get another year or two out of my computer, is there any reason to buy lion or mountain lion for this machine? I am currently on a tight budget so a new machine isn't affordable for a while. I wasn't having any issues with leopard until it stopped being supported and don't do anything more intensive than office stuff, iphoto, browsing and music.
Also will I be able to clean install snow lion from the disk I buy without my leopard disk, which is currently mia?
thanks

You could get more RAM, but that RAM gets expensive, since it is no longer mass produced.

Mac OS X 10.6 Snow Leopard would be the best Mac OS X upgrade, stay away from Mac OS X 10.7 Lion or OS X 10.8 Mountain Lion (if supported), as they should have at least 4 GB of RAM.

You won't be able to run Mountain Lion on the Macbook, Lion is the last version of Mac OS X it can run. If you're going to upgrade to Lion, you'll have to get the Snow Leopard disc in order to install it.

4GB of PC2-5300 is very cheap. Its price is still falling and is currently around $30 for 2x2GB sticks.

Oh, then I was looking wrong earlier, where I looked on Newegg and Amazon for DDR2 SO-DIMM modules and a 4 GB one cost 60 USD or more and two 2 GB sticks cost 48 USD.
