I assume you mean the conveyor dryer. What budget you have? Are you planning to expand your business in the near future? And what size you are looking for?
The price on the dryer is starting from $1500 up, for a home base or small business, some 5 ft dryer is good enough. My customer had a very good feedback on the Workhorse product. And they had a compact dryer is below $3000.
You may take a look on
this.
Beside I for my opinion, I would stay away on the used equiment, especially on the dryer, cause you don't want part of the ink is cure but part is not. Plus finding the heat elements is kinda headache.
HTH.
