does anyone have any comments on any kit cutters in the way of quality, cost, delivery times,, etc.

OOPS my bad just realized I should not have posted a response. I'll go now and get those reading lessons[:@]

Hi,
Since this is a "general " question about that service here is a general answer. Most of these services as far as I have read on RCU are providing LASER cut parts. IF the patterns or plans are good such as from CAD files(and you trust your plan) then the results are super good.
Often the serving co. provides a SHORT KIT or just the hardest parts to cut leaving simple stuff like sheating to the builder to keep costs down.
If you have not built a laser cut kit before your in for a NICE experience . They are so clean and accurate it is amazing.

ask around the CAD forum if you get a specific project in mind.

"Action Ed" from Lazer works in Wichita Falls Texas is really great to work with. I sent him my plans had my kit ready to ship in about 2 1/2 weeks, quality is really great, he will work with you all the way through. Give him a call after you visit his web site :

BTW Ed is not just a kit cutter he is also an experienced modeler and designer.
