What is the minimum capacity for an SSD to store an OS?

[NotSoHonestAbe]

I'm looking to upgrade my primary boot drive from the 80GB IDE HDD I have now to an SSD, and I was wondering, what is the minimum capacity an SSD should have to store Windows 7 32-Bit? And where can I get a good deal on a good SSD of that capacity?

Well theoretically a 32 gb should work but I would be more comfortable with a 64 gb. Dont get an OCZ drive, they are cheap but die alot. Intel, Samsung, Kingston, Mushkin etc. all make reliable drives, try and find one of those with a good deal.
