Kemp, I suggest you spend some time on http://www.theanalogdept.com/ website. It will give you detailed info on your 150. Best belts to use and where to purchase, how to oil the bearing and what oil to use, dialing in the suspension, tweaks, making an armboard, the best DIY mats, etc. SME 3009 arms seem to be the most popular arms on these tables.
If you take off the bottom cover and take a look, you will be amazed at Thorens simplicity. One of it's strong points, very simple to work on and everything you need to know is discussed in detail on the site provided above.
I highly recommend you do this maintenance yourself, it is very simple and easy and you will learn alot in the process.
The only real expense will come if you change arms. Everything else is peanuts.
Go for it!
