I think you have to purchase the type that fits your projects. The one you're looking at on ebay has both end opening as well as a side opening. I have a Chile Forge Tobasco and have done forge welding in it with no trouble BUT it's not good for large pieces being that the design is more for long pieces like blades. That's where a side opening comes in handy. So, end openings or side opening or both is one question you need to ask yourself. I love my Tobasca but there are times I wish I had the long side door too.....
