I have been just about everywhere in Pattaya, but only found 3 shops that sell multi-tools. Each shop only has one choice. Is there a big DIY superstore in BKK or elsewhere that has, or can order, from a wide range of manufacturers/models?

Among others, I would like to get a "hands-on" on these ...

Was at Hardware House in Pintong (out on the 7 motorway near the LaemChabang exit) today, they had the Fein mulitool.

They also have a shop on Sukhumvit road opposite the Ambassador Hotel in Jomtien.

Thanks. I was at the Hardware House store opposite the Ambassador hotel 3 days ago. They only had a IMPAX model at 1,519 Baht. I will try the store in Pintong soon.

In Buriram I have seen the Milwaukee M12 Multi Tool known in the USA as the Milwaukee 2426 or in the EU as the Milwaukee C12MT. At the same Buriram Builders Merchant store I viewed the less expensive Auto Mac Tools cordless multi-function AMB12CUT. I'd be inclined to buy the tool from a shop that had a real tool repair service center and access to parts if not replacement parts in stock. Fein is a fine tool brand worth checking out in my opinion.
