I own both 5350SE and A300. Both are fine for the money, which was all I cared to spend at the moment.
Several of your choices are available used on Agon:
Audio Analogue:http://cgi.audiogon.com/cgi-bin/cl.pl?ampstran&1080209535
Creek 5350SE: http://cgi.audiogon.com/cgi-bin/cl.pl?ampstran&1081703742
MF A300: http://cgi.audiogon.com/cgi-bin/cl.pl?ampstran&1081782793
MF A3.2 (A300's replacement I believe): http://cgi.audiogon.com/cgi-bin/cl.pl?ampstran&1081760599
Last one sounds like a deal.
As the Nike commercial said - Just do it.
