My first housed SLR was a Pentax LX in a Subal housing... since DSLR's came on the scene I've lusted after a housing to allow me to enjoy Pentax glass underwater again 
I am very excited to be able to use my preferred lenses underwater again!
You are all aware of the Tokina 10-17mm Fisheye.. This is actually a Pentax design;)
I'm excited to be able to use the Pentax 10-17mm Fisheye (same as Tokina but with SMC multicoating), the 15mm Limited DA prime lens.. Pentax 35mm DA Limited Macro and the Pentax 100mm WR Macro in combination with the Pentax K5 (Currently the best aps-c camera body available.. the Nikon D7000 is a close second;)
Woohoo!
