Once? I have a room full of those once things. I have to admit it does take some time to get used to the cost of strobes
This is what's going to happen.... The OP will purchase the less expensive strobe and will enjoy using it. For a while....
Soon the OP with realize that TTL is nice to have, as is a modeling light and a sealed battery compartment. Within a year the OP will decide the 430.00 isn't really that bad for a good strobe and will buy one.
It's happened to all of us at least once......
