I am a Lego castle fan. I am posting about certain sets made by Mega Bloks. Ok, calm down! Hear me out, please..
Mega Bloks produce a series of sets called 'probuilder' which are large sets of usually military vehicles - boats, planes, helicopters etc.
These sets are excellent for getting huge quantities of basic Lego-type brick pices, in tones of grey, at very good prices.
Are they the best kept secret in lego/lego-type castle MOCs?! I really think this is worth investigating and consideration.
To give idea of what is available, check out these links:http://www.graysage.com/cg/Toys/Megabloks/ProBuilder/USSKittyhawk/index.htmlhttp://www.graysage.com/cg/Toys/Megabloks/ProBuilder/Destroyer/index.htmlhttp://hubpages.com/hub/Buy-Mega-Bloks-Probuilder-Boats-Setshttp://www.miketaylor.org.uk/lego/ssd/
And the following link - from the official Mega Bloks wesbite - provides pdf instructions which include piece inventories, which is very helpful for targetting ones purchases. http://www.megabrands.com/en/customerservice/instructions.php?brandSelect=1&dir=customerservice&level=3&level2=3
Most lego-clone series of what Mega Bloks makes may be crappy, but their line of military boats in their 'probuilder' line is an entirely different matter in my view. You can find excellent prices for new and used on ebay and amazon etc.
