Aye! Aye! Aye!
I was just about to post and see Stu and I basically telling you the same thing.
Georgio you could have bought a brand spanking new 6 inch Dob - yes 150cm worth of aperture for around $350 (if that) and you can pick up second hand 8 inch Dobs. around that same amount, often here on the forum in the classifieds section.. I owned a 6" and was awestruck with what it showed me. You could even make out the separation between the rings on Saturn.
If I'd seen your post much earlier, I would have strongly advised you to wait just a little bit longer to get the extra money together. It would have been worth it.
If you change your mind, are you able to back out of the order?
Oh almost forgot, in all the panic..
Georgio, very glad to have you on board.
