Is anyone who have bought automotive diagnostic products online?

Hello everybody!! First time posting here and its because i really need help. I run a small repair shop. so I was wondering if there is some

reasonable priced car diagnostic tools that would be able to bring my garage into the 21st Century?

Recently, I am paying attention to some online shops, I found that there are a wide variety of automotive diagnostic products online, but I dare not

to buy.

Is anyone who have bought automotive diagnostic products online?
Please share some experience or skills.
Thanks.
