I agree, i would go for the Honeywell Galaxy range, like a G2-20 with radio Portal, This has everything you are looking for.
Stay away from Domonial panels though, absolute nightmares!
What system do you have installed?
Are you going to have the system as "bells only" or do you require some kind of monitoring? (key holder/police response)
If monitoring is something that you require then paying ADT is a good idea
Where do you live?
I can very possibly supply you with a system for less than a grand depending on where you live
I work for a well known CCTV installation firm
