Has anyone used any of these cheap limiters?

Drawmer DL441
BSS DP402
Sony SRP-L300
Drawmer MX30
Fostex 3070
Yamaha GC2020
Art Dual Levelar
Behringer DSP 1400p
Behringer Ultramizer PRO 1424P
Behringer MDX 2100
DBX166XL
DBX 166A
Samson S.com Plus

Has anyone gotten decent results with any of these (using as the last link in the mastering chain)? Just want to try some cheap alternatives to software limiters for fun.

Thanks!
