Wide Angle Lens for Sony DCR TRV-38??

I have been shooting a lot of wakesurfing lately and am in desperate need of a wide angle....can anyone suggest a good wide angle for a decent price??

Check out the Century Optics DS-55WA-37 .55X Wide Angle Adapter. http://www.centuryoptics.com/products/dv/55x_wa/55x_37mm.htm Please note that this is NOT a zoom-through lens!! Which means that if you zoom more than half way you will loose focus. If you are comfortable with that B&H Photo has it for $79

Another "Century Optics" option is the DS-HR65-37 .65X HR Wide Angle Converter which is $210 and does all full zoom through

Or you can look at the some of the lens from Kenko or Canon. The TRV-38 has 30 mm filter threads (got that from the sony site, but you might want to double check…!) so when you're doing a search make sure to note the thread size of the wide angle lens before buying.
