Garlic press with minimum force required
Not really an answer to your question, but a possible alternative - why not frozen garlic? 

I use a lot of fresh, but there are 2 different sorts of frozen I use too - one is Indian in origin &amp; comes as a bag of 'cubes' of frozen paste. It loses some of the punch of fresh, but you can simply add more if required.
UK pricing maybe £1.10 for 500g. 

The other type is 'european' &amp; is finely chopped &amp; loose in a bag. This is more expensive but still retains the full flavour &amp; aroma.
It doesn't cook down quite as well as the cubes. Even though the aroma is better for a short cook, if I'm doing a long cook where the garlic should 'vanish' I will use the cube-paste instead.
UK pricing closer to £1.50 for 100g.

Either is close enough that no-one could tell once it's cooked into a dish.
Effort required == zero in both cases.

I found a fairly random supermarket link with both alternatives - Tesco UK

Re comments on the question...
Both of these are significantly closer to fresh than anything you can buy in a jar.
