I'm getting paid soon! Yay! So it's time for some new pedals. Which one of the following pedals would you pick and why?

MKS GR9: http://cgi.ebay.com/CLASSIC-MKS-GR-9...#ht_7643wt_992

MKS Sylvan Lite: http://cgi.ebay.com/CLASSIC-MKS-SYLV...#ht_7415wt_992

Wellgo R025: http://cgi.ebay.com/WELLGO-TRACK-FIX...#ht_7204wt_992

They're all around the same price of $25-30 shipped. I'm leaning towards the GR9s because I wear Vans and Chucks and all them thin bottom shoes. The only problem with GR9s is that they don't look very grippy at all, but I don't know if that's a non issue or not.
