Spot weld chisels

[darkhorse]

I'm looking now at the need for a spot weld chisel.
i see two brands available , "seam busters" and " lisle" seam buster appears to be about ten bucks more for similar tools, which is better? Regardless of price and is there anything perhaps better you guys are using? And lastly, do I really need an assortment of them to do floor pans, can i just get by with the smaller straight blade ones?

thanks guys
