I went with Sherwin Williams High Solids Epoxy Paint for my floor.
I've seen it mentioned on here, and alot of good reviews on web. 4L of hardener and 4L of epoxy (tinted any colour you want) was like $135cdn inc tax.
Just finished putting it on like a month ago, so we'll see how it stands up. The 8L total did 2 coats on entire floor, plus all the 1x4 baseboards, and there is still probably 1L of epoxy and 1L of hardener left for touchups later.
Can see some shots of my $500cdn '66 beater project :P
