crookedkut,
I purchased the x-carve 1000. It was cheap and easy to put together. I did not buy any of the homing switches. I did buy the clamps. Don't buy the tool PKG. It was very basic, but for what I use it for it is great. It is not as heavy duty as some. So it depends on what you want to do with it. The 700 is smaller and I started to go with it and then measured it all and upped to the 1000. The 1000 will do a project without tiling at about 38 inches by 38 inches. So far I have not needed anything larger. The 700 would not have done some of the projects I have done.
I bought a smaller unit earlier and paid more for it than I did for the X-Carve and it was a mistake from the start as it was not large enough for what I needed unless I Tiled in X and Y directions. Set up for Tiling is a pain to me. If you make the slightest of errors when Tiling, you will pay a price.
Overall I would rate the X-Carve at a 4 out of 5.
There are Vids galore to help with the assembly and the support group is fantastic. If you email, they answer back within a very short time and if you call, you may have to wait for a tec, but not very long. They can tell you and explain to you what it is needed. If you have Team Viewer on your computer, they will show you right on your computer what you need to do, to make it work the way you want. Team Viewer is no cost. Software of your choice. I paid about 1500. The directions were good, and you have a little experience building this type of project, it will no problem. Time is the issue, about 9 hours for me to put it together. Be sure you have enough space to lay it all out on. This was key for me. Good luck and I hope this may be of some help to you.
