Need Opinion: Oneill Gooru 3mm Split Toe Boots

Is $25 a good deal for these?

The price looks good to me.. it's just that I like my 5mm Pinnacles - my feet do get slightly chilly in those if I'm sidesaddling periodically, so I couldn't imagine dropping down to 3's.  I have a 5mm john too, and wouldn't go lower than that either.  I guess I like erring more on the warm side instead of the cold side.

If you're good in 3's, seems like a fine deal.  Cheapest I find on eBay is $40.
