Hmmm, I know how Mr Ward feels.
When I was looking for a dual purpose dslr (astro and general) I went looking at pentax to go with my many pentax film SLR's (K1000, me super, mx and mz50 and many lenses). But the reality for me is that the canon product was substantially better suited to my needs. Low noise, software support and Liveview sold me.
Liveview is sooooo handy for astrophotography... I couldn't do without it.
Maybe you could put a Pentax sticker on the canon......
