Pro-ject speedbox: Is improvement worth the $ ?

Hmmm. The table will be plugged into a voltage regulator so it WILL see a steady 120V. All of my equipment draws such little power the output always shows 120V in the display, never going up or down even one volt so I should be good there. Like Kiko said, think I'll just upgrade the cart for now...... and maybe a cork mat. Was going to get the acrilic platter but am having a hard time justifying the price for a platter at 1/3rd the cost of the table. I'd rather get a cart. Maybe an Ortofon Blue.....? I have a Graham Slee coming so if a put a nice cart on the table it may be a decent analog setup.
Thanks to everyone for your opinions so far.

Sorry for the late response. I've been away for a few days.
Kiko65, I purchased the Graham Slee Era Gold mkV. I also purchased a Ortofon 2m Blue brand new but haven't received it yet. About a month ago I decided to get into vinyl for the first time. Since then I've been researching tables, cartridges, accessories, etc. I haven't spun one record yet and already I'm getting the upgrade bug. Started with a budget of less than $500. Today I almost bought a used table that retails for $1,600 new. Oh god.

The ExactPower is a waveform correction system. It actively removes high frequency irregularities from the waveform; it does not filter them. The work is accomplished by a high efficiency, pulse width modulated power amplifier.

Will a speedbox be an improvement? Don't know. Only one way to find out...

LOL. Yes, I've been doing this audio thing for a long time. I've been through my share of ups and downs, buying selling, failed equipment etc, so I know what the madness is like.
Regarding the rest of my system, I have no intention whatsoever to change anything. I'm the most content I've been in 20 years. I've wanted to pull the trigger on vinyl for quite some time and I figured what the hell, now's the time.
I've not only purchased some vinyl but have been fortunate enough to have a couple friends (non audiophiles), give me their unwanted LPs, mostly jazz, some classical and other genres.
I just fitted my table with the Ortofon Blue only to find out it's too heavy for the factory counterweight. I just ordered a heavier weight from NeedleDoctor. Whow knows? Maybe this setup will satisfy me for a while....I really wouldn't mind hearing what bumping up to the $1,500-$2,000 range would be like though.
