RE: well...crashed the avistar....
Did the FDR (Flight Data Recorder) tell you how the ailerons got shifted to the left? They were OK on prior flights, right? Had the trim gotten bumped over? Don't give up on repair yet. Would probably still be cheaper and quicker. THIS is why you should always have at least 2 planes, even if you don't have enough radios for both. I've got 4 flyable right now and a 60 size Bridi KAOS on the build board slowly going together(snail pace).
