Sorry to hear about your shipping issues.
I think you will be very happy with the 10 inch. I've had my LXD55 now for about 3 years and I'm very happy with it, perfect it's not but a very, very good scope for the price. I also have a 12 1/2 dob that I built myself and I must say the LXD is seeing more use than the 12 ".I'm very pleased with the images seen with the 10 " and have taken some pics with it and a DSI. Imaging with it is a challenge because of the mount and a trial in patience but you can see some of the pics I've taken with it here. They aren't the best in the world but do show what you can do without a lot of effort.

All of the pics of comet Holmes were taken with it and I am quite pleased with them.
I'm still learning as I go along with the scope and hope to find the time this winter to take the mount apart to help with some of the backlash issues in the geartrain. I may upgrade it to a belt drive setup to eliminate the spur gears but we will wait and see what improvement I get with the reduced backlash .
Some improvements I've done, replaced the stock finder, added a motor onto the stock focuser, purchased an adapter with a compression ring for the focuser, added a cooling fan and recently added a red dot finder which I find to be a big help

You may want to hop over here to see what they have to say about it as many members have the LXD75 also
