Starter going bad?

[accely]

Hey guys, I think my 05 H2 starter might be going bad...

Sometimes it clicks once and stops, just started doing it yesterday and it finally started after about 8-10 tries. Today it started fine when I went to the gym, but when I came out it took about 3 times to start, again just clicking once each time it failed.

Sounds like the starter? I just replaced the battery maybe 6 months ago so I can't believe it'd be that.

I looked on AutoPartsWarehouse website at replacement starters and they range from 120$ to almost $300... they all seem OEM so what's the big difference?

thanks!

edit -- found this here for 65$ seems legit... opinions? http://www.discountstarterandalterna...-12564110.aspx
