Well if you want something similar to the Fluke 289, there isn't much that can match it for features an specs and reliability. If $600USD is making you pause, then perhaps you are looking for less expensive alternatives.
The Agilent you mentioned uses an organic LED display and drains batteries like crazy. IMHO opinion the 1252B is a much better buy and I would buy it over the Fluke 289 for a reference meter as it is almost $200 less expensive.
If you are looking for an even less expensive alternative, it is hard to beat the Brymen BM869. It lacks internal logging but at $240 it is a solid performer and is CAT IV/1000 rated.
The final one I am going to mention, and probably the best buy of all, the UEi DM397. At $240, it includes a meter with almost any feature you could want, high accuracy like the rest, plus it comes with the PC cable and software for that price. For all the others it is an added expense.
If you want to spend more than the Fluke 298, then look at Dave's reviews of the Gossens, and mjlorton's review of his Metrix.
Not much else to say here....... except:
CEM is the OEM for some Extech meters, and for many other rebrands. The quality control has been abysmal. I would stay away.
