Any recommendations for mini starters on eBay?

there are 3 styles, 1 and 2 are the same but physically longer than the other in the stator, like 2 inches but both bolt up. the 3rd has the lugs on the opposite side via an extended plastic terminal that can be removed as needed. All will bolt up. The longer one has a little more power. I think the small one (black) is 1.1Kw and the longer one (red) was 1.3Kw?
