The Rayjet is our introductory brand, but it still carries the same degree of support system that of Trotec. The Rayjet 50 is a great little machine but for it's price we even recommend the Speedy 100. Rayjet uses a slimmed down software, along with lacking the Trotec speed. Now the new Rayjet R500 (130w glass tube 36x48") was just released and it's a great startup machine and has very appealing price point and an upgrade/trade-in program to a Speedy Series.
There's we have a couple Synrad tube models as well but those are 200+ wattages.
You are quite right it's insanely hard to find a used Trotec. To answer that simply, our customer's aren't trying to sell them, but buying additional systems because they've been able to grow so greatly. While I write this there is a customer here to purchase their 2nd Speedy 400 LOL
