Pentax is a nice choice. Just make sure it's not an older model (they tried to do that to me in a camera shop once with a Pentax 12x50, i.e., sell me an out-of-production model without telling me).
I think you want PCF WP II not PCF WP. (John B would know.) At $300 it's overpiced too. Shop around or try here:

I bought binos and other stuff from centre.net.au before and they have always been good to deal with, with delivery usually the next day.
