I don't have and hands on experience per say, but I have researched them on various forums. Everything I get from people that have them is that they work very well, except for the fact that that model does not have a manual mode for the BK. Don't know how cheap they were on amazon, but you can buy that model all day on eBay for 26$. The other model that seller has does have a manual mode, and you can get them for 36$. Can't remember the exact model numbers, but the one on amazon is an "a" model, the one you need I'd the "d" model, looks just like that one but it has a big grey border along the bottom.
