I got a Uni-T UT139C for my first DMM. Its been great. I decided I wanted a second meter and bought an old Fluke 8800A. Nice, but I kind of wished I'd skipped over it. My next meter was a used Keithley 2000, as was the one after that, and the one after that. Then I got a great deal on a Keithley 2700, and kicked myself for not buying another one from the same seller before they sold out. Then the seller listed one again (I think someone didn't pay after winning an auction), so I bought it. I don't regret any of the Keithleys. At least not yet, and I won't, provided I unload three of them this summer for enough to cover my costs.
As for why I got the Keithleys in the first place. I wanted to do precise tracking of some batteries I'm testing, and The K2000 series combines the precision I wanted with an optional multiplexer/switching card so I can track multiple channels.
I definitely like having two multimeters though, and so even if you have no need for a nice used bench meter, I'd suggest planning on getting a second handheld DMM before too long.
Oh, you mentioned your previous hobby had hidden costs... be very careful not to feed any latent fascination with precision electronic measurements. If you get your first >=6.5 digit DMM, it won't be long before you are after a second, and seeking out calibration standards, and eyeing 7.5, or even 8.5 digit DMMs not to mention nanovoltmeters, and picoammeters, and electrometers, and...
