£500 to spend on equipment, what to buy?

[acheekymonkeyuk]

I might soon have £500 to spend on some bitcoin mining equipment. What should I invest in?

Whats the talk of new miners coming out in next few months that will make current stuff defunct

There are no 28nm for £500 miners at the moment.

If you want to mine right now, I'd look for some second hand 55nm Bitfury stuff, it's cheap, and power efficient, 1GH/W@25GH-0.65GH/W@45GH.

These are new prices..
Bitfury 25-35GH cards £243/€295 http://www.bitfurystrikesback.com/shop/ (needs an M-Board €99 and a Raspberry Pi €35 too to get started)
Bitfury 40-45GH £410/€499 http://technobit.eu/index.php?id_product=59&controller=product&id_lang=1 (I recommend using the TL-MR3020 router €35)

I'm mining with this right now, it makes me about 40x my power bill, even if the new stuff is twice as efficient it should still make 20x my power bill in the future, as long as Bitcoin prices are similar (around £500/€600 per BTC).

If you don't pay your power bills you could mine with any high GH/s miner.
Though technically it's theft, someone is paying that bill, and you're extracting their wealth!

What about the Block Erupter Cube

When are the new 28nm gonna come mainstream

Hmm, I would suggest SCRYPT mining instead of BTC mining with that ammount.

Block Erupter Cube 30GH(220-250 Watts) or 38GH(320-350 Watts)

is no comparison to

16x Bitfury 25GH(25-30W) or 45GH(60-70W)

they use 8x more power and will be unprofitable to run 8x sooner.

When are the new 28nm gonna come mainstream

KnC 28nm Saturn/Jupiter was out Oct/Nov 2013 275/550GH (300W/600W) £3k/£6k 2nd hand, no longer taking orders (building a 20nm 3TH model)
HashFast 28nm BabyJet 400GH (400-420W) just started delivering last few weeks, suspended taking orders (4 batches already)
CoinTerra 28nm TerraMiner IV 1.6-1.7TH (1900-2100W) just about to deliver, $6000 still taking orders for May delivery.

Hmm, I would suggest SCRYPT mining instead of BTC mining with that ammount.

Like mrugala says, think about building a gaming PC and mining Litecoin instead when your not playing games on it.

With 500 Euros, I'm not sure your options are too open here.
You might be better off throwing $200 into BTC, $100 into LTC, and then $200 between a few other alts.  Hopefully you hit big with one and then you can cash or convert to BTC.

Get some nice risers..

Its cheap, I'll give you that. Will it get you your money back. Not in a hundred years.
