Hi, Deadguy welcome to signs 101, thay would be a good way to go start out with a plotter which is a small investment, you will also need software to run the plotter, also you will need to know how big of jobs you intend to do, there are many diffrent sized plotters, 24 inch being the most popular, also you need to watch out for what you buy some of the cheap stuff on e-bay is just that cheep stuff, the better plotters will cost you a little more but worth it in the end the cutting quality is much better so when you cut the letters and graphics come out clean and are easy to weed.
the better machines are summa, allen datagraph, graphtec, roland, Ioline
I have a summa but the others are just as good or some may say better..
then you will need software, if you are just going to cut you can use programs like flexi, signlab, corel draw, etc. if you buy a new cutter, from a sign supply place you can usally get a bundel where you get the cutter and software together, if you looked on e-bay you have seen ads from sign warehouse, go to there web site signwarehouse.com and look at what they have...they sell a house brand and graphtec, (who makes there house brand) this will give you an idea what it costs to get started..
also if you google sign supply you may find a dealer in your area that you can go to and get a demo they will show you how it works and what you need as far as the software you can look here at the form on software to get opinons on which is best, I belive that flexi, or corel draw is the most
popular, but they are not the only choices, then if you want to get int printing later you may need to update your sofware but the versacamm is a good machine that is what I have it works great, ....I think that it would be best to find a supply company close to you so you can get the help and support to get stared in the right direction...just my opnion , good luck chopper....PS. in answer to the machine to machine question it is not dificult to switch from one to the other as long as you have the right software..I belive that flexi is easy to switch back and forth, I have sign lab and it allows me to be printing on one machine and cutting on the other at the same time, I belive that flexi will also do this..
