I agree with the price being good with the mount and all a nice little 8" will do the world of wonders when it comes to photography.
with the left over do yourself a huge favor and get a motorized moonlight focuser, trust me on that one you will save yourself A LOT OF GRIEF, and make the over all astrophotography experience more enjoyable!
with the focuser
325 with the rigel hand controller

There will be a few bob left over for the other bits and pieces (you do have a guide camera yes?)
