They have a nice selection and pretty informative website, but no prices. You need to 'get a quote' so I called and talked to a rep, and felt that they are not a small/hobbyist customer oriented. The guy was nice but it was clear that they don't care for the low cost/entry level market. I did find some interesting things: he confirmed what we knew already, that the most popular and therefore best value ball screw size is 5/8. Another useful information was that there are three manufacturing classes, in order of increasing accuracy and price. Standard rolled thread is accurate to 0.004in/ft; precision rolled good to 0.001/ft, and ground thread better than 0.5mil/ft ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
