So I am making a table top but all I need is the base... what would be a good cost effective option. would they have somthing at my local music shop or do I have to buy a eureka table base?

You could modify a drum stand, but by the time you figure out what you need to do, buy the extra materials and actually do the work, you'll wish you had gone ahead and bought the Eureka base.

Buy the Eureka base and save a poor innocent drum stand.
