It was just an old school HT3B with a 26 cm, had it during college. I knew the setup wasn't going to be ideal, but was pleasantly surprised by how quickly the primary lit. The secondary would start to light at around 1500 RPM and the primary would start making steam at 1750. For being a college budget set of compounds it was pretty nice. If you're on a budget then I'd recommend grabbing one with either the 16 or 18, then when you can afford it you can easily swap it to an S300.
