Looking for a large adjustable desk/table frame?

I'm looking to build a gaming table thats adjustable for playing different games. I've looked on amazon and I can't seem to find any frames that will fit a 44"x60" tabletop. The biggest I have found will do 33" on the short side, Anyone know of any available for this? Preferably the 4 leg kind, just for stability. Not a super crazy budget, the highest I'd like to go is $250. The highest I will go is $300. Thanks for anyone that can help me out with this!
