If you are bonus whore and dont mind putting in a little extra effort, this is what I would do:
Deposit 50k in Fidelity through either United or American airlines frequest flyer account. You'll get 25k bonus miles. Lots of money market and CD options at Fidelity earning over 5%.
Deposit 25k in TDAmeritrade through Starwood Preferred Guest sign up program. Get 20k SPG points which can be converted into 25k airline miles on most airlines. TD has CD options for 9-12 months that earn over 5%
95k in a 1 year CD earning 5.4%
AmTrust Direct First Fed Direct
Keep the remaining 30k in a high interest savings account earning 5% or better. Be on the lookout for other promos/bonuses that may pop up (for example, Fidelity had a $100 depsoit bonus for a 10k new money deposit for existing accounts some time back).
If you travel and know how to use miles wisely, you can usually book flights where the value of a mile is over 2 cents a mile. You could take the 75k you would invest at Fidelity and Ameritrade and earn .25-.5 higher elsewhere which would result in $187.50-$375 more interest income, but you will be taxed on this amount. I put the value of 50k miles at around $1000 and they are not taxed.
Of course, all this assumes you are in not in the highest tax brackets.
