Welcome to ECF, Cory! Vision Spinners (and similar such devices from other manufacturers) usually run in the $20-30 range. I'd second Maiar's suggestion that you also look at something like the eLeaf iStick 30W, which runs between $30-35--they are not heavy or bulky by any means, will provide a longer battery life, and also offer you the ability to accommodate other tanks if you so choose.
