They would be nice, however, because there would be no penalty for withdrawals and they would grow tax-deferred unlike the IRA which there is a 10% penalty for withdrawals before 59 1/2. You can contribute $4,000 per year to an IRA which you can deduct from your taxes and that can be invested in just about anything. You can open an IRA with just about any online broker but remember that it is "retirement" savings. Any money that you are saving to use before 59 1/2 should be put into a Non-Qualified savings or brokerage account. Check out:
