1/48 there's one game in town- Monogram/ Revell. It's a big model and would be a lot of fun to build. If you set your mind to it, you can find one. Probably around $ 100.00.
I have never seen the 1/48 liberator for $100 if you look at Revell.com, they have it listed (I think) at about $45, which is a fair price for that kit. Some of the details on it are a bit on the soft side, but everything you need is there, and the fit is not too bad
