where is the best deal on welders?

Looking at either a Miller 180 or Hobart 187. Where are you guys buying these from? and how much are you paying? also, what is a mid range size for a gas bottle? and how much do they run? Thanks.

I've bought a couple off of ebay.  you can get free shipping and no tax.  and they are dropped shipped locally.  They only took 2-3 days to get here.

i went to airgas and bought the esab multi master 260. i got a deal on it cuz it was last years model. i got it for $2500 

I found the hobart you wanted at  northerntool.com for $669.99 with free shipping. Seems like a good deal to me. heres the link  http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_200328799_200328799
