The sticky pen AKA the Pentax O-ICK1 is manufactured by a company that recently introduced their product to the general market. Previously I think only certain factories (Leica, Pentax) used them in house and pentax sold it as their own solution. I forget the company's name or the name of their product, but it is identical to the pentax part. Leica used that product, so it can't be bad. I think the problem is that you have a sticky surface that picks up dust and perhaps people were not cleaning them properly with the pads before and afterwards. It seems like the reports were that it would sometimes leave sticky gunk on the sensor. I never bought one because of reading that. Then I thought about it for a while and it seems like they are probably using pads with old adhesive and that the adhesive is sticking to the tip rather than pulling dust off of it.
I've used a giottos rocket blower (the big one) for some time now and never had a problem, though I have have forced a piece of dust under my old k-7's sensor one day with some really aggressive blowing, so that's something to consider. You should blow it a bunch of times before you use it to clear out any potential dust inside the blower. Maybe that's what the person that had problems didn't do. I think they have a filter on the intake end, but that's about it. As always I guess YMMV!
