009 Decoders part 2

So, onto Lenz and their silver (£25) and gold (£30) minis.  Each has just 2 function outputs but measure in at just 11mm x 9mm x 3mm.  The gold supports high frequency PWM for my coreless motor in Linda, but the silver is pretty basic (800mA peak, 2 functions only) and is therefore expensive in comparison with other makes.  In fact I think you pay quite a bit more for the Lenz name and I'm not going to invest in that, so in 'Dragon's Den' parlance - 'I'm out'.  Lenz stuff is here.
LokPilot v3.0 8 pin DCC Decoder 52611

This £20 decoder is good for coreless, has 4 functions, back EMF and all the usual 'good stuff'. It's a bit bigger though at 23 x 15.5 x 6.5 mm and only handles just over 1A maximum.

The manual is here.
Zimo mx68L

20 x 10 x 4 mm, support for coreless motors and 4 functions, 4A total load and for £20 - now you're talking!  Manual here  

Thanks to a commenter, I have noticed that this is a function only decoder, the equivalent with a motor function too is around £30 and out of my price range anyway.  But if interested click here.
ZTC Diamond 255

But the award for the mother of all decoders goes to ZTC's diamond 255 decoder.  This comes in at a super £11 via their ebay sales (£13 direct).  It has 4 functions, 2A max, variable frequency PWM, back EMF and dither.  It's 20mm x 12mm, so small, but not tiny. The manual resides here
