::::::Getting a sphere doesn't really seem like a crappy level to me, since you get access to every spell on that list based on how high your character level is, which means under normal Tome rules your spells known is automatically progressed regardless of what levels you take before or after entering this class. I also think (but am in no way sure) that higher access to spheres comes with each new sphere you receive (so if you have three spheres in total you would have Expert Access with your first sphere, which is all usable at will if I remember correctly, Advanced Access with your second Sphere and Basic access with your third. So the progression using the normal Tome spellcasting rules is far quicker and less complex than the one provided here, hence my initial consternation at the spellcasting table. This also allows you to not have to waste a turn recharging your spells and just continue on as usual, making the class much more streamlined and actually Wizard-level. If you want to keep the recharging and still ditch the table, you can make it so you can recharge one of the sphere SLA's that is only available once per day, thus compensating for the obvious limits in your spell list. Just for the sake of reference, I got my info on spheres from the [[Tome of Fiends (3.5e Sourcebook)/Spheres and Feats#Fiendish Spheres|Tome of Fiends]], so I'm not sure if you're following that or something else.
