Another thing to do whilst you are waiting, is to learn processing.
The photos you take will need to be stacked, stretched adjusted etc. and this is a big learning curve.
While waiting/deciding on gear, head over to here:
http://www.mistisoftware.com/astronomy/index_fits.htm
You can download some actual raw captured images and start learning how to process them, and get a headstart before you get images of your own.
These are separate LRGB captures that have already been stacked etc.
For Planetary samples, click here:
http://www.skyimaging.com/astronomy-videos.php#top
You can download them and learn how to best process the planets and the moon.
There is another site that has sample DSO files for going from scratch, I'll try and find it and post it here.
Processing is as big a part of it as capturing the images in the first place, so you may as well start getting up to speed on it before you lash out on the equipment, and see if it really is your cup of tea.
