Hi Laura,
You didn't state your budget, so this will be a guess on my part.
You can try looking at Stewart MacDonald's website in their "tuner" section:
http://www.stewmac.com/shop/Tuners/G...ad_tuners.html
You'll find Schallers starting around 50 bucks, and you can move up to Waverlys starting around 230 or so.
And it will go up from there. Gotoh makes a nice, not-too-expensive tuner available from LMI:

Hope this helps!
