press question

I noticed homier is selling a 6 ton A frame style press for $39.99. http://www.homier.com/default.asp And do a search for 6 ton shop press. Is this press to small for most AK builds? It definitely is a good price - but I remember most use a 12 or 20 ton press. I currently have access to a press, so am not really in the market for one - but figured for the price this would be a good one if it would work for doing AK builds.
