Generally a transistor test is a sign of a poor quality meter. It would be better to buy one of those cheap transistor multi-testers from ebay for around $20 and get a multimeter that actually is built correctly.
You can get the UT139C which is built safe enough for electrical work around the house, also has temperature, back light, non-conact voltage detector, and for $50.
If you insist on spending $150, with the money left over from a cheap transistor tester, you can buy the Brymen BM257s which s one of the best multimeter in its price class, if not the best.
http://www.ebay.com/itm/Brymen-BM257s-Digital-Multimeter-6000-count-Brand-New-Fluke-alternative-/200922627340This ebay store belongs to our good friend iloveelectronics on the forum. He also sells the UT139C. I have both meters and have no hesitation recommending them. PM iloveelectronics for maybe a better deal if he can outside of ebay.
The other meters, have their pluses and minuses. The UT71C is a nice meter but I don't think it gets you much more than you have with the UT61E. The DM510A, if it is a Greenlee, is a rebranded Brymen. Some of the Greenlees an be purchased on ebay for a good price, but not all of them are as good as a price as the Brymen directly. The Fluke 115 is not that good a buy, not many features and missing uA if I remember correctly. The rest? Well I don't wave time to try and figure out which models and manufacturers they are.
