Query - $ for $ - what CCD / OTA would be best to capture planetary nebulae and why?

Simple question - but I expect it takes alot of know how to get the right answer for this. Put simply dollar for dollar - and ignoring considerable need for a capable mount and dark skies - what telescope design and CCD pairing would be best to capture planetary nebulae and why?

Lets say you a Paramount ME and you wanted to put a OTA and CCD on it to capture only planetary nebulae. What choices would you make if you had say 1) $5K to spend 2) $10K 3) $15K 4) over $20K.

I'm interested to know how experts would handle this task, what factors are of primary vs secondary importance and where the bulk of the spend goes at a price point - into the CCD or into the OTA.

Many thanks for your thoughts guys!

Matthew
