Murf, yes a good transmitter is better than adding a jack because you can use it with all of your radios.  The gold standard used to be the SSTRANS 3000 kit but he quit making them a year or two ago.  Other options are build your own (note, Bill Harme who used to supply parts has passed away):

Buy a Spitfire transmitter from the UK (search for reviews first):

Look for a used SSTRANS 3000 on eBay

My buddy has modified some very early Talking House units to accept a small jack and they work pretty good.  If I didn't have my SSTRAN I would probably just use one of his, and his is much easier to change the frequency on.  He sells them at Kutztown and other meets but they're small enough to easily ship.... I think he gets about $100 for one:

There are at least a dozen other transmitters or kits out there but those are the ones I'd consider today.
