How many jumps do you have?
What type / size are you jumping at the moment?
It sounds like you're very new and I would suggest renting if you can instead of buying at this time. As an example, my home DZ offers these rental sizes to allow us to downsize safely when we're ready to do so.
Navigators: 280, 260, 240, 220, 200
Sabre 2: 210, 190, 170
Navigators are student canopies and are very forgiving for landing. I injured my ankle on the 4th jump, walked with a cane for a week and when I came back 1 month later, I was scarred of the ground.
I'm the same weight as you but it took me 24 jumps on a N240 to be able to time the flare properly. As soon as I was nailing the landing on every jump with different wind conditions, I felt confident that I could handle a smaller canopy. For me, there was little differences between the N220, N200 and S2 210 and I quickly ended up on the S2 190.
I remember that I hated to rent gear, I had bruises from every jump but it made more sense financially to rent until I was stable in sizes. I bought my first rig with a Pilot 168 and the piloting skills foundation came from the additional time I spent under the N240.
