Welcome to the forum!
A good place for you to start would be in the FAQs and General Information section on this site.
Scroll down and look under “FAQ: So where do I buy lockpicks and what do I need to buy?â€
If you do decide you would like to buy some picks, you can try
www.lockpickshop.com, which is a sponsor of this site or
www.lockpicks.com.
I myself deal with lockpicks.com and I'm very pleased with the results and customer service they have given me over the years.
There is no need for you to go overboard just starting out. A basic Southord set will suffice. Something in the $20.00 to $30.00 USD range, anywhere from 5 to 9 pieces.
I prefer the stainless steel picks with reenforced handles, but everyone is different.
When you get stuck, take the time to do a search on the issue you're having, as there are many helpful articles and people here to help you.
Enjoy your new hobby!
