Well, I'm making a basic mining rig, 600mhz which is up gradable when I get more money. Is buying/making a mining rig worth it? I will be able to get it up to 2ghz in a few months.

Depends on electricity costs and if Bitcoin will continue to go down or not.

The short answer is bitcoin - no, altcoins - maybe.

what's best to mine sha or scrypt?

Unless you've invested a lot in to an ASIC-chips, it will be way more profitable to mine Scrypt based coins.

As to answer your original question, it depends a lot on what kind of computer you have.

I would suggest that you look into Alt Coins. I was confused by the metric that you are using (mhz and ghz), did you intend to describe that you are making a rig that will have 600 MH/s of capacity? If you do some research online, you will find that there are many web sites that can give you some earning calculations for Alt Coins. I recently began mining Alt/Scrypt coin and had to build several mining rigs, I find that the difficulty levels even there are rapidly rising.

Therefore, to address your initial question. I would say that buying or building a mining rig can definitely be worth it as long as you clearly understand all of metrics and details that comes with the territory of mining coins. This would include as another poster mentioned : Electricity Cost, but could extend to trading, choosing the right coin(s), etc..

Good Luck!

Anything less than a Th/s is not going to get you the ROI to mine bitcoins IMO.
You can try mining some altcoins with this rig of yours though.

Thanks for the info bud.

I will be using a rasberry pi with 2 usb block erupters, they only mine sha cryptos, so won't be able to mine scrypt.

Is There any where that are selling custom build mining rigs for LTC or similar??

Has anyone heard of crypto industries?

Try looking on E-bay, there is a lot out there because the market is growing and growing

That's a good idea

Seems worth it. Grab a board, some pcie risers, some cards and put it all together, they sell on ebay for way more than the cost of the hardware. Tempted to build them and sell them...

Nice for mining altcoins which could be exchanged for BTC.

Just input your hashrate and wattage and find the most profitable coin to mine.

Depends on your rig as to whether to do scrypt or SHA.  Usually now it's scrypt if you can get comparable hashes to if you were mining SHA (divided by 1k).  Take a look at the multipool middlecoin pools if you're purely interested in short term profit.
