Never know til you try. Ebay is a gem for kit buying. I've bought close to 100 kits off Ebay and never regretted it, all for under MSRP. Those kits just don't exist anywhere else. I do hope Trumpeter does a Fitter in 1/48.
-There's also buy/trade/sell/swap sections on other forums. I bet if you put in a request at ARC, Hyperscale, or somewhere else you'd have that kit in a week.
