vixen vc200l, lightweight probably the lightest of the four (unless the gso offering is light), supposed to have tight flat field, at f9 or thereabouts the DSLR uses will struggle on faint stuff unless they are cooled. not much chop for planetary.... ive had one. and the FR didnt fit even though it had vixen written all over it.
gso rc, new kid on the block, first results from paul heases shot of eta look promising, problem is that a bright object and so far no-one else has really produced the goods that make me say yes ill buy one. time will tell ( but id want the 10 inch) focuser probs easily rectified. same goes for the dslr at f8, i will wait for those that have one and a DSLR to realize this, then there might be a cheap one available.
meade rcx well i leave that to rat he has produced exeptional results with his... but he does use an adaptive optics thingy which helps too. plus FR readily available which helps dslr users
celestron 9.25 proven performer and does a reasonably good job of deep sky AND planetary. again FR available. at the moment this is the one i would choose... but watching closely the RC
Rats comment of widefield... refractor , long focal length some kind of reflector is fair comment.
