The Voron 2.4 is very popular, and 300mm is probably the most popular 2.4 size, so availability of parts is good.
I decided to go 250mm since the Railcore is already 300mm and it takes a lot of space and I don't need that large a print volume very often. The Trident is a little easier and lower cost to build, but the differences are not large. For those interested, the 2.4 has a fixed bed at the bottom and the CoreXY gantry is supported by four belts driven by reduction belt drives so it won't drop when power is lost. The Trident has the same gantry fixed at the top and the print bed rises on three leadscrews with independent motors. Both the 2.4 and the Trident do auto-tramming using the 3 or 4 motors and a sensor. Various sensors are supported. Both designs use linear rails and 20mm extrusions and are made to be enclosed and print up through ABS and ASA materials by heating the interior with the heated bed. Voron is a design group that makes these designs and publishes the CAD, BOM and instructions. They don't sell kits or printers.
I haven't heard anything about voronkits dot com. I heard the Voron group was having some trouble with their trademark. I don't know the details, but the Voron design group does not sell kits or printers, so it is not from them.
I would stick with vendors that are on the Voron Discord to be safe. LDO kits have been top notch but they sell out quickly, almost like Raspberry Pi's. My DIY collection for the Trident has a lot of LDO parts kits like frame, motors and hardware. LDO makes a lot of parts for Prusa.
I would have saved money by buying a kit. Collecting parts separately is more expensive with multiple shipping and smaller bulk discounts. There were no complete kits when I started. Now there are a number of them. None are endorsed by the Voron group, they have no control over the kits. The highest quality kits sell out quickly, but even the lower quality kits are getting pretty good. Buying a kit and changing the things you don't like is a good approach for most people. Collecting all the parts is a task.
