5.something shares of Berkshire Class B stock at 79.00 a share. ING Sharebuilder has a great plan where every Tuesday you can buy stock at 4.00 a trade and add new shares at a rate of 1-4.00 a trade. They let you have fractional shares so you could invest 500.00 worth of cash and they would round out the spare change to buy fractional shares. Most major railroads have a ESOP program where you can buy shares at no commission direct from the company but I would still recommend ING Sharebuilder because you can move your money around faster and you get a single statement. Someone should create a Class 1 railroad index fund (like GLD or SPYDER) where you could buy CSX,CN,CP,NS,BNSF and UP in one security and one phone call.
