Yes Mig is definitely cleaner; no clean up. However FC allows a little better penetration which can matter on a 110v unit at the upper limits of it's ability. On the other hand, Mig does gauge metals with ease. I think both would be handy to have around if all possible.
OP, I've had a little WeldPak for a couple years now that runs FC only. I've used it a lot. It definitely has limitations but it was my first welder and a gift from dad. It'll stick around no matter what. I'm currently starting to look for a bigger FC/Mig too. I think you'd do fine to find a 140 if the 110v unit is the one you can run at your place. Read reviews, as many as you can find.
If 220v is remotely an option, jump up to the 180 sized units. Price wise, they'll go anywhere from $450-$800 new and used.
