$240 is one of the more affordable flash/incidence meters. Many of them run $300 to $600.
That said, there currently are the Sekonic L308 that costs about $219, and the Gossen Digiflash 2 selling for $184.

Some older flash/incidence meters dating from the days of film have limited ranges that makes them a bit less convenient for digital.
Some years ago I bought a used Sekonic L358 for around $200. It is a recent-enough model that's been updated with ranges appropriate for digital. It also can be set up to show 1/10 stop, 1/3 stop or 1/2 stop increments, and more. The L358 is a now-discontinued model similar to the L308, except that the L358 can optionally be fitted with radio modules for certain wireless triggering systems. I've got modules for Radio Popper and PocketWizard systems that fit the L358. Now the least expensive flash/incidence meter I'm aware or that has wireless triggering is the Sekonic L478 that starts around $365. In addition, it doesn't use interchangeable modules. Instead it's dedicated to work only with one system or another.
Brands I'm familiar with and comfortable recommending include Sekonic, Kenko and Gossen. I'm not as familiar with them, but Shepard/Polaris seem fine, too.
In the past I've used several Minolta models, too (IIIF and VF). Some of these later were sold under the Konica-Minolta name, after the two merged in 2003. In 2006 Sony bought the photography division of Konica-Minolta, but spun off the light meters to Kenko, who still manufacture them today.
The old Minolta, along with Sekonic, Gossen and others from the same time period, are examples of meters that were originally designed for use with film, which have limited ISO ranges by today's standards and may have some other limitations. They certainly can work, just aren't as ideal for use with digital as a modern meter might be. KEH has more than 20 used flash meters:

Adorama and B&H have some, too:

There also a bunch of flash meters on Amazon... though a lot of them are brands I've never heard of. I'm also a bit wary of buying on eBay, though sometimes there are great deals there.
EDIT:
penndragonn,
While radio/wireless triggering is convenient and eliminates some wires that people might trip over... all flash meters I'm aware of without that feature have a PC socket for WIRED triggering. You just need a long sync cord, which you may be using anyway, to connect to your camera. The sync cord needs to be long enough that you can take the flash reading right where the subject will be located.
