hi RossG,
i was in a similar situation to you a few months ago apart from i originally started looking for a sr4. hears the thread i started at the time
http://rib.net/forum/showthread.php?...ght=sr4+family
the general impression i got was that that it would only be ok in very calm water and be very cramped
in the end i ended up buying a zodiac pro 500 that I got for just over my budget and it came with a lot of extras, so i'm sure you will find something within your budget!
