Velocity Deep Vs are an option.
And H Plus Son offers a 42mm aluminum rim.
Of all these, the H plus son seems to the only properly "deep" option. IMO 30mm hardly qualifies as deep these days. There are also a ton of options at the 30mm range. Aforce al33, boyd altamont, hunt, dt swiss, zipp. Probably a ton more. I have a 30mm alloy rim. I think it looks fine but as rims and tires have gotten wider even 40-50mm rims have started looking a bit blunt.
