Computer keyboard

Has anyone found a keyboard which has large keys. Dad has large fingers (sausages we always call them!!) and when he has tremours he really cannot use the computer. I have done a google search and found a couple of very expensive options (£79,£94) but they are outside the budget. Any tips would be appreciated. Currently looking at sorting out some of the accessibility options for him to prevent mistakes but large keys would be the best option. Thanks

Hello again Dilruth,

If you have a disability living centre near you they have computer adaptions and answers to most problems, I hope that you have because they have all sorts of equipment to cover most situations.
best wishes
