I'm looking for opinions on a couple different pairs of Pentax binoculars and wondering who may have experience using them. Here they are:

DCF HR II, 10x42 (new model)

DCF SP, 10x 43 (new model)

DCF WP, 10x 42

The WP is being discontinued, but has received rave reviews. The other two are new models. Clearly the SP is superior, but costs about 2x what the others cost. I'm mostly trying to determine whether and extra $250 is money well spent and/or whether I'll be happy with the lesser expensive models.

Thanks for any input.
