If you're asking if it will be worth it, because of effectiveness, it will be good for starting seeds. Keep the light within 2"of the canopy at all times, even touching. The stand works well for that because you can easily raise the light as it grows. I highly recommend that if you get this, that you get them to put bulbs that are appropriate for vegetative growth, (assuming you're doing vegetables and tobacco) in it instead. You want higher colour temperature, ie. 6500k, no lower than 4200k. Those lights have a lower cost of operation than most other setups, and if you go away, they are better than HID, because they won't dry up the soil as quickly, and they are less of a fire hazard.
As for how much it's worth? The brick and mortar indoor gardening store near me sells a 48"t5 strip light with reflector for $65 Canadian. They can put any frequency bulb I would want, seeing as I'll be there in person. The stand goes for $25. I don't know how much the float tray costs, but I'm thinking seeing as there are no shipping costs, you would do better to go to a real store, and support your local economy. You might see other things, and get advice, etc. For example, last time I was there, i had a long conversation with a professional about fertilizer. Also, those strip lights are compatible with a bracket that allows you to connect four of them together on that hanger. Being there in person, you will be able to ensure what parts you get are expandible, and compatible.
Don't overestimate the cost of buying locally, you might be surprised.
