I am getting ready to purchase new blades and am curious what bandmill blades you use and what sharpening service you have had luck with.

Wood-Mizer blades, and I let them do the sharpening. For 6.50, it's a no-brainer.
As for sending the blades out for sharpening... Good in theory, but since so many of the problems you will encounter sawing will come back to blade problems, it's a little risky. With customer service on a downward spiral these days, the time you'd have to spend hunting lost blades or trying to fix a problem would be counter productive.
The reality is you need sharp blades, enough to work all day, and a couple of extras in case you hit nails. They need to be set right and on hand. You can hope somebody else will take care of it the way you'd do it or you can just take the time to learn to do a good job sharpening them yourself.
If you are like me and do 20+ blades a week, then find a re-sharp service that can take care of you and do a very good job on the blades as well. I use WM Re-sharp and have a deal where a bad blade or worn out blade is replaced one at a time, so my inventory of blades remains the same. I have over 80 0.045 10 degree blades and at any time 30 to 40 are in the system of going to get sharpened or on the way back. I keep no less then a 2 week supply of sharp blades on hand.
If you get to where you need some special cutting blades and have lots of different sizes, then getting your own equipment makes sense. But to spend 3 grand to sharpen and set 50 blades a year makes no sense.
Keeping your blades all the same brand and style makes your life easier. Different brands work different on each mill. My mill did not perform well with Simmions, but the blades were good blades. I tried some el-cheapo blades for $10 that were to be throw-aways, but the cut was not always good and life was poor and cost soon exceeded the cost of WM blades, which I have grown used to using. My blade cost last year was less then $0.02 a bdft using WM blades and Re-sharp. How easy it is to use the service and how well the blades perform are key to me. If I have time to sharpen blades, then I have time to saw and make money making sawdust. All sawing and no play make me a dull boy any day.
