I currently own a Matrix 310 and a regular Matrix riser and limb assembly that I swap out for hunting season to hunt with a matrix 330. I will be purchasing a BD330 in a few weeks. I like the simplicity Excalibur crossbows offer as far as maintenance goes, along with the accuracy and lifetime warranty. I also like the fact that I can change my own string in less than 2 minutes and know that poi will still be the same as long as I use matching strings - which is one reason I buy strings in pairs and shoot them both in until they settle in.
