Interesting. I, too, live in Houston, and started a Texas 529b plan for my child. But I just got a note in the mail that they are changing the managing company for the plan, and the expense fees are going up! (of course) Now, I think I will switch to the Vanguard 529 plan, which I think is based in nevada, and has a $3,000 minimum.
I am just stashing $100/mo into the account, and by the time my daughter is in college, it should grow to around $45k or so. Unfortunately, I project 4-year college tuition will be $150k by then (would need to save $400/mo from birth). But I'm not sure I want to stash away more $$$ than this into her account. After all, my daughter's future higher education desires are an unknown at this point, and I can always pay for her additional expenditures with money from another source. From what I can discern from MMM, he doesn't use a 529 plan, but will get his son's back as far as seeing that he doesn't graduate from college with soul-crushing debt.
As for appearing "poorer" in ER to get more financial aid--you are right, it is a moral dilemna.
