Very interesting someone would sell you a scope without a mount. It's a Newtonian I take it?
If you want to do things on the cheap (and handy with tools), try make a Dobsonian mount for it. There are a number of plans freely available on the net.
If you are after an EQ mount, an EQ5 or EQ6 would be better. EQ2 and 3 won't be up to the task.
