In reply to Helonia VS Helvetica - Curious dearth of information:

I am detecting a trend in my hunting. Fonts that are not cheap to buy (like Helvetica and Swiss 721) are offered in many weights and widths, whereas free fonts that are Helvetica-like are usually offered in one or two, like regular or bold.

I did find an interesting font site: http://www.fontyukle.net/en/

but I worry about downloading from unknown sources. Has anyone used the above source?
