Plug in one or two of these into your present outlet: http://www.marinedepot.com/md_viewItem.asp?idproduct=TW39013 They also have them with cords on them (inline). Just search GFCI in the search box at that site.
I picked up a few of these and I can tell you they work faster then the typical gfci outlet does. I've had 2 trips in my new house and both were plugged into gfci outlets which never tripped. Matter of fact, one of them kept tripping the other night and I discovered a heater was leaking current into a QT tank. So they are pretty cheap, super easy to install and work really, really well.
3. If after putting some type of gfci at the outlet (1 or 2 above) you trip the circuit breaker because of to many watts you could change out the breaker in the box. If you are presently at 15 you should be able to go to a 20 without problem. If you look at the wire going into the slot where the breaker is you should be able to tell if it's 12 or 14 gauge wire. If 12 you could probably push it to a 30amp breaker if the 20 wasn't enough. I however wouldn't try a 30amp unless you have 12 gauge wire.
PLEASE DO NOT Put 20 amp breakers in without 12g wire! This is code!
Also do not use 30amp breakers without running 10g WIRE!!! Also Code!
Please listen to these numbers... undersized wire with oversized breakers are asking for a disaster!!
