I just ordered a carton of 50 for $73, free shipping, lol.
Though FYI: Tony HAS stated that he is looking into getting some made for the sidesho/902 from his factory. Which would be awesome since I'm sure they'd LOOK better but to me it looking slightly oversized is nothing relative to the ease.
The only thing I'd say is you read a lot about how many times you can refill them, etc. I'd stay away from that. I opened one up and took out the wool after about 5 days of reusing the same one and it had baked in crap in there that was NOT pleasant. When you're burning that old dried up fluid it can create some less than happy chemicals. Don't be cheap if you use them, smoke them for 2 days and chuck them, it still only costs 75
a day at that rate, lol
