In my opinion you get what you pay for. That being said, how many times are you going to use it? I use mine for peering across bean fields and wishing those dang deer would just walk my way...
Check out a local pawn shop and see what they have. You can take it to the front of the store and look thru the glass to make sure it works for you. Lightly bump it a few time and see if it holds it's position, sometimes on the cheaper models w/tripods, they get stripped out.
Wally's' World of Cheap imports and Harbor freight may have something not to pricey, they are worth checking also.
