You're new here, so you may get a pass from all the flaming typical to respond to a post like this.
To be honest, effects is all about your personal taste. Best advice you can get from here is to watch and read the effects threads and watch youtube videos of anything that interest you. If you buy something you think you may like, but end up hating it, a supporting membership here can always help you trade and/or sell it on here. There's always Ebay too.
Go to the "Bass Guitar Forums" and click on effects. Spend some time there. You will find your answer and more things you want to try then your budget can ever afford.
