Orion Optics UK have fantastic optics and I recommend them highly!

Yes OO's secondary mirrors are excellent.

This post in OO's Yahoo group on the subject of secondary mirror coatings is well worth a read.

I'm looking to pick one up also.. mind you I have a worry about sticking it with the offset??

[jonstarrysky]

offset. I guess same for same is simplest if it is an upgrade. But I have on best authority that the offset is unnecessary. Secondary holder stalk/ post can just attach at the centre of the back of the sec mirror. On my stock secondary it is attached with an off-set, causing the secondary to be shifted away from the foucsser. I am glad OO secondaries have good reputation. I am buying a 1/10 wave one. Do ppl feel the 10mm thickness is OK ?
