Is there an ART's rental near you? They offer true rental vs buy and repay later. The real deal is if you can get it rented and returned quick enough the hold on your card is only 24 hours and then canceled out.
Actually, the puller you linked is one of the better ones. NOT a t-handle, which means you can put a socket on it and put as much force as your socket will allow.
I know you are young and new to things. I applaud you for going the extra mile to ensure your start is a success. This is but one step of many.
Keep it up and you will have a great riding career!
