I'm looking at them as well and for me the cost of filters is the turn off. Looking at those QHY filters, apparently the red filter isn't parfocal with the GB filters and there is no L filter so you'll have to buy a real set of 2" filters anyway

From my manual wheel experience, you can refocus between colours but you don't want to shoot all L then R then G then B, you want to shoot across the filters to randomise the data collected. So many times I've shot LRG and got to blue with the manual wheel and it's then clouded over

Regardless, the qhy is still in the lead for me as I believe this production run of the sbig is sold out so you'll be waiting till February for the next batch. Similarly the starlight xpress one has no dollar value on it but they are taking orders for a mid january release.
