the $8 meter from Harbor Freight works great for biasing amps. If you spend more than that for a meter, make sure it has auto range detection, otherwise it's not worth the extra $'s. I picked up a couple of the HF meters for $4 each off of a sale table. They're also great to have around for other purposes. I've also seen the cheapo meters sold on line by MCM and other places. You can order from Harbor Freight online too.
