I have been using reaper for a few months, payed $60 australian dollars for my 'non commercial' licence.
In my humble opinion it is the best VSTi and VST FX host around. I have used herman seibs VST host, and still like it as a patch editor/librarian.
The audio routing is phenomenal coming as I did from various versions of logic, much more flexible. REAPER also gives you complete control of the rendering process which I don't believe any other application does.
On the helpful forum there have often been criticisms of the midi editing capabilities, and Feature Requests for various things found in cubase, logic or sonar. Coming from logic was a shock as I made heavy use of all the logic editors, and now had only piano roll or event edit. The major midi playing card that REAPER gives you is VST and JS midi FX, this is gives you the power to make limitless non-destructive editing in real time, which is very much the philosophy of REAPER.
I have been using REAPER for more than 8 builds now, and I will stay as long as the program remains healthy.
