I've had a stellarvue SV90TBV since 2008. It's a great scope, and the one I tend to pull out the most often as it only takes a minute to set up on my vixen porta mount. It's small enough to use as an airline portable scope, I took it to Cairns to image the total solar eclipse back in 2012.
You get great support from Vic Maris. I spoke to him directly when I got my scope (I thought the objective had a small scratch, it was just a fleck of paint that had come loose) and he gave me advice on how to fix my problem.
It will probably be the last scope that I sell if I have to sell some of my scopes
