Rega Planar 3 upgrades help.

When I had a Rega, mine improved when put on Cadas blocks (2 in front and 1 in back) to eliminate the factory installed feet. 

Tangospinner has upgrades that are well made and affordable. Check him out on ebay or Google him directly.

Go to vinylengine.com and get all the info about Rega tweaking.

I had a P5 years ago and found the subplatter and belt the best bang for the buck upgrade. I did find speed noticeably faster(even with the optional power supply)which was one of the things that wore me down to invest in a more substantial table.

Hindsight, all the other mods I did where a waste of money if you are more than a casual listener. 
All the Rega tables are great for what they are and the upgrade thing becomes a slippery slope after addressing the subplatter issue IMO. You may find-wow, if the subplatter made such a difference, what if I change the...???$$$$
Since you got the table for cheap, investing a few bucks may be worthwhile. I would leave the glass platter alone, as it contributes to the Rega "sound" and look for a real cork mat and maybe replace the rubber band suspended motor with the upgrade as well. 

Another consideration, invest as much as you can in a phono stage to hear what the the table is capable of if you don't already have a decent one. Happy listening!

I have the Graham slee reflex M.
I already got a deal on motor kit for $140 and I ordered the reference band.
I will keep the glass platter because rega signature is important to me.
Anyone familiar with structural mods upgrades ?
I was encouraged by a local analog guru but I want your opinion as well.
Thank you

consider spending as much as a you can on a LOMC and using any money on additional mods on good records and call it a day.

The Rega upgrade bug can have you upgrading endlessly until you realize an entirely new/different table and cart is the real solution.
