Well, thats more or less how I feel about it, but I'm sure there are others who would disagree. There are some valid reasons to start with some low cost equipment but in my mind the negatives outweigh the positives. My feeling is, that if you have any success your going to basically upgrade immediately and honestly once you get a higher end machine, what ever your starter equipment was will be either collecting dust or sold for pennies on the dollar.
Also, keep in mind that purchasing the printer isn't the only thing you have to consider. RIP software, color management tools, media etc. will cost you a bundle. There is a steep learning curve too. I've seen people make the dangerous assumption that running a solvent machine is alot like desktop printer. Its not, there really is a tremendous amount to learn and digest. Also, there is alot to the imaging and design software before you even get to the print stage, no matter how good your equipment is its garbage in, garbage out.
Here's what I think a realistic budget would look like.
RIP software: Wasatch, Flexi or Onyx poster shop
$3k-$4k
Design Software
Photoshop CS3 $600.00
Illustrator CS3 $500.00 (Corel X3 is less, but I'm not sure how much)
Used 64" Solvent Printer
Mutoh VJ or Mimaki JV3 (I'm a Mimaki guy)
minimum around $10k after shipping, replacement of worn components etc. Realistically, figure $12k-$15k
Used 64" Cutter with Reg Mark Detection
Graphtec or Mimaki around $4k
6-8 ink cartridges, flushing cartridges (necessary if your machine is used IMO), wipers, dampers etc.
$1k
Some starter media, vinyl, compatible lam and banner material
$600.00
Figure for the above easily $20,000.00
That doesn't include any color management tools or a laminator. That can easily add another 8-15k right there.
The reality is that if you want to be able to make products that compete with guys that have the heavy duty tools, you have to shell out for the big toys. A better option might be to start by sub-contracting and once you have a book of business, and are familiar with design and file preparation for printing, draw up a business plan and see if spending $20,000 to $30,000 makes sense.
The flood of seemingly capable "outdoor" printing technologies hitting ebay at low prices has created a sort of artificial price point in alot of peoples minds about digital printing. Just like cheap vinyl cutters, buying a used inexpensive printer is not going to be a magic key to success. There is a lot of work, additional money and time involved in making a digital printing outfit successful.
