If you can stretch your budget a bit, have a look at a Harmonizer. Self calibrating, auto-ranging and sampling. The best!

I've just done some research....Also, if watching the pennies, look at the Morgan Carbtune.
I've had one for years. Few mechanical parts to go wrong and seems accurate enough. I had one of the very early ones that used mercury! Can't think why they stopped that.
The one I have now uses stainless steel needles and is very stable with less problems with storage.
I have a Harmonizer listed on ebay at the moment if you are interested.
