Or you can order some silentstepsticks. The best upgrade ive done to my printers.
They run smoother and a lot quieter
silentstepstick your tube vid

Sorry bigfilsing , what does that have to do with the jumpers?

Industrial best practice is to NOT tin wires that are to be terminated with screw terminals.
The reason this is so is that the differing thermal expansion rates of copper and solder cause a problem. The solder in the tinned wire end expands more than the copper (brass) terminal and a big peg in small hole causes the softer metal to yield (it gets softer with increasing heat as well). When the temperature drops later the parts contract again but now the tinned wire end is smaller than it was and causes a bad connection.

Instead use wire ferrules, also referred to as bootlace ferrules.

Getting back to the original question - a more reliable RAMPS - you could always spend a bit more money and get one that's been made properly: RAMPS Premium. The only things I don't like the look of are the fuses - it's a shame they didn't fit real fuses.

That premium ramps talks a good talk but....
16volt caps under pololus, means you also cant use this ramps with 24v.
Also it doesn't have a 5V regulator on board to avoid relying on the often-overloaded one on the Arduino Mega. That and the 16V limitation make it a fail IMO.

So - apart from the fuses, voltage and regulator it should be fine! 
In reality though - if someone really wants a RAMPS board and plans to use it normally then it would be a decent purchase.
Mind you, at that price, it's a fair way towards the cost of a 32-bit board (assuming that the 32-bit board is also made properly).

Do ANY Ramps have 5V regulators on board????

I am not aware of any RAMPS boards that have voltage regulators on board.
I suspect that when RAMPS was first designed several years ago, nobody used GLCDs or servos on their 3D printers, and everyone made small printers that only needed 12V supplies. Also the 32-bit processors cost more than the 8-bit ones did. In that context, the RAMPS design made sense.

Then that board in question isn't a "fail" because it doesn't have a regulator, is it? I wish they did but ...............

Yes it is a fail, because it addresses one of the deficiencies of RAMPS in today's context (inadequate mosfets) but not the others.
