I remember a previous thread that indicated a few posters who collected die-cast model cars. I haven’t acquired anything recently in my collection but was browsing the ‘net and found a few manufacturers which I have never experienced (most of my collection is by Minichamps). Does anyone have experience in either of the following? I’m curious how the quality (workmanship and decals) compare with Minichamps:

Spark
True-Scale
Hot Wheels (I’ve seen a few of these in local shops but don’t have any first hand experience).

Thanks and feel free to PM!
