Cheap improvement to sg90 servo

Hi all,

Can I get some advice on servos please. I'm building a standard simple arm driven by SG90 servos. They're great because they're cheap and accessible.

From a design perspective I'm expecting the lowest part of the arm (the shoulder?) To have more weight/strain than further up the arm, so I was wondering if there was a standard servo which was still cheap and accessible but a bit stronger than the sg90?

Can anybody recommend something?

I'm based on the UK if that affects the purchase options.

Many thanks

At the very least you should be using metal geared servos

Thank you @UKHeliBob that pushed me to discover the towerpro website.

There's an awkward mix of power, size and price to compare. The mg90d ones do seem a little more powerful at a similar size but harder to find at a good cost.
