Tony P. - Keep firmly in mind that I know next-to-nothing about crossbows, but I bought a Blazer soft case, extra Center Punch arrows, Scorpion Venom rail lube and bowstring fluid, extra regular Alpha-nocks, and some lighted nocks. The nocks just slip into place and are only held by friction, so I lost one nock quickly. The nocks are easy to change into the lighted version with the purchase of translucent nocks (green, etc.) and the led/battery stick. I think it costs about $5 per arrow to convert to the lighted nock.
